Subject: [dpdk-dev] [PATCH 5/8] net/iavf: add workaround promiscuous disable
Date: Sun, 27 Sep 2020 07:26:23 +0000
Message-ID: <20200927072626.28374-6-robinx.zhang@intel.com> (raw)
In-Reply-To: <20200927072626.28374-1-robinx.zhang@intel.com>

In scenario of Kernel Driver runs on PF and PMD runs on VF, PMD exit
doesn't disable promiscuous mode, this will cause vlan filter set by
Kernel Driver will not take effect.

This patch will fix it, add promiscuous disable at device disable.
